A knee-operated hand washbasin is a type of sink or washbasin that can be activated without the use of hands. Instead, it is operated by a knee or foot pedal that allows users to control the flow of water without touching the faucet. This design is ideal for settings where hand hygiene is critical, such as healthcare facilities, laboratories, food service areas, and other high-traffic environments. By eliminating the need for hand contact, knee-operated hand washbasins can help reduce the risk of contamination and the spread of germs, making them a hygienic and practical solution for a range of applications.
